ASIC Canaan Avalon Nano 3 / Nano 3S — Home Bitcoin Miner with Built-in Heater Function

08/04/2026

The Canaan Avalon Nano 3 and its more powerful version, the Nano 3S, are compact ASIC miners designed specifically for home Bitcoin mining. With ultra-quiet operation (33–40 dB), a tiny footprint, and a built-in heater function — mining heat warms your room — these devices are ideal for home use. In this article, we'll cover the specs, setup, and how to connect to the Kryptex Pool, including solo mining mode.

🔧 Who is the Avalon Nano 3 for?

  • Beginners looking to start mining Bitcoin at home without excessive noise.
  • Apartment and office owners who value compact size and quiet operation.
  • Enthusiasts who want to try solo mining and find a block on their own.

💎 On the Kryptex Pool, SHA256 Canaan Avalon Nano 3 / Nano 3S ASICs can mine BTC, FB, XEC, DGB, BCH, BSV, BC2, and QUAI SHA256.

✅ Merged mining of BTC+FB is also available — mine Bitcoin and Fractal Bitcoin simultaneously.

Solo Mining on Canaan Avalon Nano 3 / Nano 3S

Solo mining is a mode where you mine independently: if your miner finds a block, you receive the full block reward with no sharing. The pool fee for solo mining on Kryptex is 1%. What is SOLO Mining?

To enable solo mining, use the wallet format solo:WALLET_ADDRESS.WORKER in the Worker field instead of the standard WALLET_ADDRESS.WORKER.

⚠️ Important: For coins with lower network difficulty — FB, XEC, DGB, BCH, BSV, BC2 — the chances of finding a block are significantly higher, making solo mining especially worthwhile for home miners.

Canaan Avalon Nano 3 / Nano 3S Setup

Package contents:

  • Canaan Avalon Nano 3 or Nano 3S ASIC miner.
  • Power supply with Type-C connection (optional).
  • USB Wi-Fi adapter (Nano 3S).

Before installation, place the device on a flat, well-ventilated surface.

  1. Power on the miner:

    • Connect the USB-C power cable to the miner.
    • The device will boot up in approximately 1–2 minutes.
    • Device status is shown on the small built-in display.

  2. Set up the configuration app:

    • Download the Avalon Family mobile app from the App Store (iOS) or Google Play (Android).
    • Open the app and tap the menu icon.
    • Select "Add New Device."
    • Tap "Search" to find your Avalon Nano 3.
      • If using a wired connection, tap "Manually add running device" and enter the IP address shown on the front panel display.
    • When the device appears, tap it to connect.
    • Enter your Wi-Fi network name (SSID) and password, then tap "Save."
    • The device will reboot and connect to your home network.
    • Log in using the default credentials root for Nano 3 and admin for Nano 3S, and create a secure new password when prompted.

  3. Configure pool settings:

    • Navigate to Mining → Pool Settings
    • Enter the pool details (pool address, wallet address, and worker name)
    • Worker — Specify wallet and worker name in the format 1KVms9T3RKmz6sVCeUPFPFgpYzMj9LZ5rE.Nano3, or solo:1KVms9T3RKmz6sVCeUPFPFgpYzMj9LZ5rE.Nano3 for solo mining, where:
      • 1KVms9T3RKmz6sVCeUPFPFgpYzMj9LZ5rE is your wallet address
      • Nano3 is your worker name (Latin characters and numbers)
    • ⚠️ QUAI SHA256 uses PROP mode with no SOLO option. Blocks require two weeks to confirm.

  4. Make sure to fill in all 3 pool slots with the same pool settings. Click Save to apply the settings and wait for the ASIC to reboot.

  5. Verify miner operation:

    • After the reboot, wait 5–10 minutes.
    • In the web interface, you'll see the current hashrate and pool connection status.
    • Check that your worker appears on https://pool.kryptex.com

💡 One pool address is listed per coin. Additional regional addresses can be found on each coin's pool page at pool.kryptex.com.
